Tools and Supplies Needed

  • 13 mm wrench/socket (for oil drain bolt and screen)
  • 8 mm wrench/socket (for oil filter cover)
  • Torque wrench (capable of low settings, as small fasteners are used)
  • Small pick or needle-nose pliers (for removing the oil screen)
  • Fresh OEM oil filter
  • 1 liter of high-quality 4-stroke oil (e.g., 10W-50 for KTM spec)
  • Drain pan
  • Funnel (to prevent oil spills during fill)
  • Clean rags or shop towels
  • Contact cleaner (to clean oily surfaces and drain screen)

KTM 350XCF Model-Specific Call-Outs

  • KTM uses magnetic drain bolts, which attract and collect fine metal shavings. Inspect closely each change.
  • Low torque values on bolts and filter cover: overtightening may cause damage. Drain bolt and oil screen: 10 Nm (7.4 ft-lbs)–Filter cover bolts: 8 Nm (6 ft-lbs).
  • Oil capacity is approximately 1 liter–do not overfill.
  • KTM oil screens can get stuck; use a small pick for removal if necessary.

Step-by-Step Oil Change Procedure

  1. Warm up the engine:
    • Start and run the bike for 2-3 minutes to warm the oil, allowing it to flow out more completely.
  2. Remove the skid plate (if equipped):
    • Many KTM 350XCFs have a simple release pin; rotate and slide off for quick access to the drain bolt and filter screen.
  3. Drain the oil:
    • Place your drain pan under the engine.
    • Using a 13 mm wrench, remove the magnetic drain bolt on the left side of the case. Allow the oil to completely drain.
    • While draining, inspect the magnetic tip for any metal particles and wipe it clean.
  4. Remove and clean the oil screen:
    • Locate the oil screen next to the drain bolt. Remove using the same 13 mm wrench or a T-handle.
    • If the screen doesn't pop out, use a pick to gently coax it free.
    • Clean the oil screen thoroughly using contact cleaner to remove debris and metal shavings.
  5. Remove the oil filter:
    • The oil filter is usually housed on the front or left side of the engine case. Remove both 8 mm bolts on the filter cover.
    • Carefully pull out the old filter using pliers if necessary. Allow excess oil to drain.
    • Check the filter for excessive metal or debris as an indicator of engine health.
  6. Install new filter and reassemble:
    • Lubricate the new filter's O-rings with oil and install it in the proper orientation.
    • Replace the filter cover, ensuring the O-ring or gasket is seated correctly.
    • Tighten the cover bolts by hand first, then torque to 8 Nm.
  7. Reinstall oil screen and drain bolt:
    • Insert the cleaned oil screen and torque to 10 Nm.
    • Install the cleaned drain bolt, torque to 10 Nm.
    • Double-check for any leaks or residual oil.
  8. Add new oil:
    • Remove the oil fill cap on the opposite side of the engine.
    • Using your funnel, pour in exactly 1 liter of recommended 4-stroke oil.
    • Replace the oil fill cap securely.
  9. Prime oil system and check oil level:
    • With the bike off, hold the kill switch and bump the electric start to circulate oil before the first start.
    • Start the engine, let it run briefly, then turn off and check the oil level as specified in the owner's manual (use sight glass or dipstick if equipped).
    • Add oil if necessary, being careful not to overfill.
  10. Reinstall skid plate and clean up:
    • Snap the skid plate back in place.
    • Use contact cleaner and shop towels to remove any oil residue from the frame and engine.

Additional Tips and Best Practices

  • Always use OEM or high-quality filters and oil that meets or exceeds KTM's spec.
  • Keep a record of oil changes for maintenance tracking.
  • Do not overtighten bolts; many threads in the KTM 350XCF's castings are delicate.
  • Inspect for oil leaks during and after your first ride post-change.
